Power Requirements
2.1
The TWR-P1025 is designed to be externally powered through barrel connector J2 from a 5V@5A DC
supply. The barrel connector is manufactured by SWITCHCRAFT with part number RAPC722X. The
mating plug should have an inner diameter of 2.1mm and outer diameter of 5.5mm.
polarity of the barrel connector.
The 5V input is used to generate all voltages on the board. Additionally when used with TWR elevators
and other TWR peripherals, the TWR-P1025 provides 5V and 3.3V supplies.
There are several expansion options on the board that allow external boards to interface to the
TWR-P1025, such as the mini PCIe connector, USB ports and elevator expansion. As these plug in cards
have variable power requirements as well as numerous population combinations the Power capability of
the different expansion interfaces and the core board are listed in
power from the external supply should be considered when adding plug-in devices or using the elevator
expansion.
